It depends on the specific situation and the character's personality. Some heroes might have moments of fear but overcome them through their determination and sense of duty.
A series of fire prevention and extinguishing measures should be taken in mines that are prone to spontaneous combustion and spontaneous combustion coal seams. These measures include setting up observation stations or observation points for spontaneous combustion, arranging them in rock formations or coal seams that are not prone to spontaneous combustion, adopting retreating mining, and not leaving any roof protection coal. In addition, it was necessary to prepare a special design for mine fire prevention and extinguishing, and adopt technical means such as injecting mortar, injecting noble gas, spraying chemical inhibition agent, etc. to implement active prevention. The mine should also establish a natural combustion monitoring system to detect and discover changes in gas concentration and temperature in a timely manner, and carry out early warning and measures to improve. Comprehensively consider the management of the goaf after mining, the fire prevention and extinguishing needs of the adjacent working faces and adjacent coal seams to ensure safe mining.
It could be about a character in the My Hero Academia universe who defies the traditional concept of a hero. Maybe they don't have the typical flashy quirk but still manage to be heroic in their own way, like using intelligence or empathy.
In a My Hero Academia fanfiction, Gohan could be seen as a hero from another dimension. His moral code, which is similar to the heroes in MHA, would make him a natural fit. He could also train the students in new ways of combat, using his martial arts skills combined with his Saiyan abilities.
Yes, there might be some in the realm of horror or supernatural young adult novels. For example, in some fictional universes, the concept of a corpse spontaneously combusting could be part of a mystery that the young protagonists have to solve. It could be related to dark magic or some kind of scientific experiment gone wrong.
Sasuke's powers could potentially be adapted in interesting ways in the MHA universe. His Sharingan could be seen as a unique quirk. For example, it could give him enhanced perception abilities similar to some quirks that allow for better combat prediction. He might be able to analyze an opponent's moves and fighting style just like in the Naruto world, but it would be framed within the context of MHA's hero - villain battles.
Goku's powers would be a game - changer in the MHA universe. His ability to fly would be unique among the heroes there. His Saiyan rage mode could be like an extreme version of a quirk awakening. But he might also have trouble fitting in at first. He's used to a more straightforward fight - or - be - fought world, while MHA has a lot of rules and regulations for heroes. However, his pure heart and desire to protect would surely make him a beloved hero.
Saitama's overpowered strength would likely be a huge disruptor in the MHA world. His simple yet extreme power of being able to defeat any enemy with one punch would make him a top - tier hero instantly. Genos, with his advanced cybernetic enhancements, would also be quite formidable. He could potentially be part of the development of new support items or hero gear in the MHA universe, given his knowledge of technology. And his combat abilities would put him in the ranks of the stronger heroes there.
